N Ka mining and a

1. In terms of warranty, n card is generally guaranteed for 3 years, while a card is usually only guaranteed for 1 year
in terms of eth, a card generally needs to brush the BIOS to achieve the highest computing power, and it needs to install a special mining driver
the N card is easy to operate, and the driver can be installed at will. However, the price performance of a card will be higher than that of N card after digging eth
however, in terms of mining life, if eth can't dig in the future, a card may cost a lot. For the time being, a card can only dig Eth and Zec. Zec has proced professional mining machines. In the future, it may not be cost-effective to dig video cards. There are really few currencies that a card can dig. N card is different. Although eth is slightly lower than a card, n card supports many algorithms. There are more than 100 counterfeit coins that can be g. One day, Eth and Zec collapse, and you can continue to live by changing any currency. Aiminer supports both a-card and n-card mining.

2. Dig with n card, you can't even collect the electricity fee... If you want to mine, you'd better use a card honestly

3. Hello, the mining of bitcoin is actually doing distributed computing, and the strongest point of graphics card is floating-point computing. A card and N card are more suitable for floating-point operation than a card. N card should spend more energy on rendering, and a card has more Alu units than n card. At this point, a card is 2-3 times faster, so mining speed with a card is faster

4. A card has more process processors, and its general computing power is stronger than n card. The architecture of a card is more suitable for mining. N card is OK now, but the effect is not as good as a card. This is a fact
let's see what others say.

5. It's Sha. This is the security mechanism of bitcoin. All transaction records should be packed and divided into blocks, and Sha hash should be calculated. Only blocks with a specific hash value can be recognized by the network. Each block contains the hash value of the previous block to form a block chain. If there are more than one branch chain at a time, only the longest chain is recognized. The counterfeiting of small computing power cannot catch up with the long chain. You can't fake Transactions unless you have 51% of the computing power. Therefore, the more scattered the computing power is, the higher the total computing power of the whole network is, and the more secure the network is.

6. Yes, bitpai supports usdt. You can mention Omni, erc20 and trc20. In the future, EOS and usdt on algorand will also support it

7. It depends on your currency, bitcoin a card and Ethernet n card

8. Before 12 cards mining, an card must be used to mix and match. This is mainly e to the scheling and management mechanism of windows. However, such stability will be poor, and scheling will bring certain performance loss. As for installing drivers, it is more likely to be a nightmare. In fact, with the advent of ethos mining operating system and Yingtai's full support for ethos, It's very simple to realize 12a or 12n. Both efficiency and stability are greatly improved. Therefore, of course, 12a or 12n is preferred.
